After doing some more flow testing and temp testing, i think i can control the pressure and temps down to -20c at 42-45% glycol for benchmarks, i think -12 will be the limit for full load continuous operation with 1 GPU.
But to get sufficient flow at G1/4 i will need to add pumps.
- two pumps in series and remove CPU jet plate giving a fluid flow:
Chiller > Agitator pump > RAD > twin d5 in series > CPU > GPU(s) > Chiller
with Jet plate in, the pressures spike when flowing enough.
- one pump for CPU with jet plate still in
- one pump for GPU
- common return to chiller.
Has anyone run Glycol like this before? what was the solution for jet plate restrictions?
